Learn how to set up a network at your home or office. In this course, Martin Guidry discusses the hardware you'll need—from switches to modems—and the specifics behind using both wired (Ethernet) and wireless (Wi-Fi) methods to connect the computers and equipment in your network. Then he shows how to share files between computers and briefly discusses email and print servers, explaining how to manage connections to those services with DHCP and DNS addressing. Martin also reviews issues you might encounter when working in a mixed (Windows/Mac/Linux) environment, and provides tips on setting up an Internet connection, as well as configuring security and local-storage options for your network.
